SABIIA - Sistema Aberto e Integrado de Informação em Agricultura (Sabiia)

Shell elongate, dark fleshy brown, with large white riblike nodules and a white infra-sutural line; whorls 10, the apical ones a little eroded, smooth, the next 2 with rather indistinct ribs, the rest with conspicuous white nodules, which become larger up to the last whorl; on this whorl, which is somewhat oblique, they are smaller on the ventral side, it shows a very large nodule before the aperture and a second row of much smaller ones, which are not visible on the upper whorls. The surface of the shell is covered with faint spiral lirae, which are more distinct on the nodules. Suture linear, irregular in consequence of the nodules of which there are 9 on the last whorl, besides 12 of the second row, and 6 or 7 on the upper whorls, where they occupy...

Descriptions of new Melanidae

Ano: 1889

URL: http://www.repository.naturalis.nl/record/508703

Amongst the Melanidae of the Leyden Museum, many species were unknown to me, so I submitted them all to the judgment of the late Dr. A. Brot, who declared many of them to be doubtful, which I have indicated in the Catalogue of the Museum by a note of interrogation; a few others, however, seemed also to this much regretted authority to be new to science and so I ventured to describe them as follows.

Catalogue systématique des mollusques (gastropodes prosobranches et polyplacophores)

Horst, R.; Schepman, M.M..

La collection conchyliologique du Musée d’Histoire Naturelle des Pays-Bas est d’origine très hétérogène. Au premier lieu elle dérive du Cabinet de Zoologie, d’Anatomie Comparée et de Minéralogie de l’Université de Leide, qui surtout sous la direction du professeur Brugmans (1786—1819) s’était énormément développé¹). Une autre collection d’objets d’histoire naturelle, sous le nom de „’s Lands Cabinet” était conservée au Trippenhuis à Amsterdam. Ces collections, combinées avec le Cabinet du Prince Guillaume V et la riche collection d’Oiseaux de C. J. Temminck, forment le noyau du „Ryks Museum van Natuurlijke Historie”, institué par décret royal du 9e Août 1820. En 1822 le Musée s’enrichissait des collections, formées par le Professeur C. G. C. Reinwardt 2)...

On the habitat of Nanina inquinata v. d. Busch

Ano: 1908

URL: http://www.repository.naturalis.nl/record/508285

The habitat of Nanina (Xesta) inquinata seems still somewhat uncertain. Philippi who described the species for the first time (Abb. u. Beschr. neuer oder wenig gekannter Conchylien I, pag. 10, pl. 4, Helix tab. I, fig. 4) gives Java as locality, on the authority of Mr. Winter; this is followed by Pfeiffer (Monogr. Heliceorum viv. I, pag. 46). The species was not found by Zollinger and has only been mentioned by Mousson (Mollusca von Java, pag. 16). Reeve (Conch. 1c. fig. 399) and even still Clessin (Nomenclator Heliceorum) give Java as locality, though not one of the rather numerous explorers of this isle, had afterwards collected this species. Prof. von Martens (Ostas. Landschn., pag. 207) suggests, after seeing a young specimen in the collection of...

Description of a new species of Dolium

Ano: 1895

URL: http://www.repository.naturalis.nl/record/508690

Shell ovate, inflated, rather solid, narrowly umbilicated, with an elevated spire; whorls 5½, convex, with spiral ribs and concentric hairlike striae. There are about 23 ribs on the last whorl; the 3 uppermost of them are narrow, the other ones rather flat and broader, with narrow interstices, in each of which runs an intermediate lira. Nucleus apparently smooth; aperture oblong, its right margin thickened by an internal rib. Interior of aperture pale yellowish-brown with two other ribs (former lips) and grooves corresponding to the external ribs. Columella straight, with a small white callus, partly covering the umbilicus. Externally this shell is brown, variegated with white; moreover numerous brown spots accompanied by white ones, adorn the last half of...

On a new variety of Leptopoma manadense Pfr

Ano: 1893

URL: http://www.repository.naturalis.nl/record/508554

The specimens of a lot of a Leptopoma, collected by Baron von Rosenberg at Gorontalo, Celebes, have the general appearance of some varieties of L. vitreum Lesson, but their columellar margin is simple. I had compared them with the species of the genus known from Celebes, but I could not identify them with any of these. So I sent a few specimens to Prof. E. von Martens and asked his advice, and this author declared them to be a variety of L. manadense Pfr. (As I had compared them with typical specimens of this species agreeing with the figure in Pfeiffer’s Novitates conchologicae, Vol. IV, pl. 128, fig. 9, I did not come to this identification). The specimens indeed agree rather well with the figure of von Martens’ Ostasiat. Landschn. (Pl. 2, fig. 8), but...

On a collection of Land- and Freshwater Mollusks from Taliabu (Xulla-isles)

Ano: 1899

URL: http://www.repository.naturalis.nl/record/508665

The Mollusks recorded in this paper, have been collected by Mr. J. W. van Nouhuys on Taliabu, one of the larger Xulla-isles, and were presented by him to the Leyden Museum of Natural History, together with a few other species from various localities, amongst which latter are however no new species. As the only record of Mollusks from the Xulla-isles is that of Xesta citrina var. by Wallace, mentioned hereafter in my note on X. halmaherica, I thought it would be interesting to enumerate them all, instead of describing only the new forms. I think the number of species existing in that island will not be exhausted by these 17 species, the more so as the second part of the collection contained several species not represented in the first lot, but the number...

On a collection of Shells from the Moluccas

Ano: 1906

URL: http://www.repository.naturalis.nl/record/509122

The shells mentioned in this paper, were, for the greater part, collected by Prof. K. Martin on his journey in the East Indian Archipelago, which was undertaken with geological purposes. Another series was brought together by G. W. W. C. Baron van Hoëvell, Resident of Amboyna. This second series contained only a few species, which were, however, represented by a large number of individuals. All these specimens are presented to the Leyden Museum by Messrs. van Hoëvell and Martin. I have included two species from Celebes, though this isle does not belong geographically to the Moluccas. The most interesting part of the collection, consists in the large number of smaller species from a cleft in coral-limestone on Saparoea. From this isle only a few species...

Description of a new species of Oliva

Ano: 1893

URL: http://www.repository.naturalis.nl/record/509246

Shell oblong-cylindrical, spire exserted, with an obtuse apex; cream colour with a reddish-brown net-work, leaving triangular spaces, and with blotches of a more purplish tinge beneath the sutures and round the middle. The 3 spiral whorls unspotted, the two next with a reddish callosity occupying the lower part of the whorls. Basal part not divided with a few brown spots. Columella straight, with small whitish plaits, some of which are bifid. Interior of the aperture rose colour. Total length 16, breadth 6, length of aperture 11 mill. Hab. Strait of Larentoeka near Flores, collected by Dr. Semmelink.

On a collection of land and Freshwater and Marine Mollusca from Waigeu, Ceram, Pulu Weh and Java

Ano: 1890

URL: http://www.repository.naturalis.nl/record/509446

The Mollusca enumerated in this paper, have been collected by Dr. L. F. de Beaufort during his stay in our colonies; the majority is from Waigeu. No new species have been named, as the few specimens which are probably new, are in young or in poor condition, but some varietal names have been applied to forms which differ from the types by shape, or which, as for instance in Xesta aulica Pfr. have not been designed by names, as has been done for X. citrina Lin. many years ago, by E. von Martens. I have to thank Mr. G. K. Gude for assistance in naming some doubtful specimens and a few other authorities for the same or for loan of specimens. The few marine species have no special interest.

Neritina (Clithon) subocellata, v. Martens, MS

Ano: 1901

URL: http://www.repository.naturalis.nl/record/509285

With the species of the Genus . Neritina, which I received for revision from the Leyden Museum of natural history , I found three specimens of this form, which Prof, von Martens, after specimens in my own collection , thought to be new and named it subocellata; but as far as I know it has not yet been described. With the approbation of the Conservator of the conchological department of the Museum I will now give a description. Shell nearly globular, delicately striated in the line of growth, with a few striae in the form of folds near the suture, and with microscopic spiral striae. The colour is greyish olive-green, with small blackish spots, which are rounded or triangular, sometimes flow together and vary greatly in size and number; they are mostly...

Land- and freshwater Shells collected by Dr. H. ten Kate in Soemba, Timor and other East-Indian islands

Ano: 1885

URL: http://www.repository.naturalis.nl/record/508818

The shells collected by Dr. ten Kate, are from localities which were still very imperfectly or not at all explored. To the latter category belongs the isle of Soemba, which has furnished a few very fine and interesting new species. Other species, though known to science, are remarkable for the novelty of their localities or because the habitat was not yet ascertained. Considering that Dr. ten Kate travelled in behalf of the Dutch Geographical Society and that his chief occupations consisted of geographical and ethnological investigations, the number of species presented to the Leyden Museum must be called important. With respect to the literature, I must remark, that I have usually cited: for the Landshells, the second volume of the Zoological Series of...

A new Potamides

Shell pyramidal, slightly decollated, thin, fragile, moderately shining, blackish-brown, remaining whorls 6½, inflated, with a deep suture; sculpture consisting of flat ridges separated by superficial grooves. Of these ridges there are 5 or 6 on the upper whorls and about 17 on the last whorl, where they reach to the base; the ridges are crossed by more or less distinct lines of growth, which produce here and there small granules, especially towards the upper part of the whorls; last whorl with a varix opposite to the margin of the aperture or slightly backwards. Aperture ovate, outer margin expanded, thickened internally, sinuous and ascending above, produced in the middle, ending in an obtuse angle below; columella with a thin smooth callus, with an...

Bijdrage tot de kennis der mollusken-fauna van de schelpritsen van Suriname naar de door den Heer Voltz gemaakte verzameling bewerkt

Ano: 1901

URL: http://www.repository.naturalis.nl/record/508741

Terwijl de Fauna onzer Oost-Indische bezittingen, wat de zee-Mollusken betreft, vrij volledig bekend mag heeten, en vele der daar levende soorten, tot in de kleinste verzamelingen voorkomen, zijn die der West-Indische Kolonien nog veel minder verspreid. Toen ik werd uitgenoodigd, om een partij schelpen uit de schelpritsen van Suriname te bewerken, was het dan ook niet zonder aarzeling, dat ik die taak aanvaardde. Het hoofddoel waarvoor deze opdracht geschiedde, is echter door mij bereikt, daar het mij bijna zonder uitzondering gelukte, te constateren, dat alle vormen uit de schelpritsen afkomstig en door den Heer Voltz verzameld, nog in West-Indië leven, en dus tot zeer recente vormingen behooren. Behalve in mijn privaatverzameling, kon ik bij een herhaald...

Description of a new species of Unio

Shell elongated, rather compressed, very inaequilateral, the umbones laying at about one sixth of the whole length of the shell, rather smooth, with numerous fine concentric striae; umbones little prominent, decorticated in the adult, in half grown shells with conspicuous radiating folds, extending more or less over the disk of the shell; moreover a few radiating grooves occupy the anterior part of the shell, and microscopic radiating wrinkles of the epidermis cover the posterior slope; epidermis reddish-brown in the adult, yellowish olive-green in the young ones. Upper margin slightly curved, anterior margin rounded, slightly protruded below; ventral margin incurved, posterior margin forming with the upper one a more or less obtuse angle, regularly curved...

On three Eastern Mollusks

Ano: 1897

Shell fusiformly ovate, yellowish, with brown spiral ridges. Whorls about 6, the apical ones, which are slightly eroded, appear smooth, the rest rather convex, depressed near the sutures, vertically ribbed with large swollen ribs of which there are from 10 to 14 on the penultimate whorl, and spirally ridged with 4 or 5 waved ridges on the upper whorls, with finer intermediate ones. On the last whorl, the ribs and waves become obsolete about the periphery; this whorl is encircled with a large number of spiral ridges of which from 10 to 12 form conspicuous brown lirae, with from 1 to 6 intermediate ones. Aperture occupying more than half the length of the entire shell, ovate, pale blue within, lip thickened exteriorly, internally with about 10 ridges forming...

Zoological results of the Dutch Scientific Expedition to Central Borneo

Ano: 1891

URL: http://www.repository.naturalis.nl/record/509408

As the reader will see from the head of this paper, the collections are principally made in the interior of the island and therefore almost entirely restricted to terrestrial and freshwater forms. Seven new species have been obtained, while many others are very interesting with regard to the geographical distribution. The few marine specimens, all belonging to common species, have been obtained by Dr. Hallier, the botanist of the expedition, on the Coast of Sambas and the opposite island Lemoekoetan.
